Problems solved by technology

Because waste mineral oil contains impurities and moisture, it does not have frost resistance, even if a small amount is added to diesel oil, it will greatly affect the freezing point of diesel oil, and the northern part of my country is in a low temperature state for half a year, so this method cannot be used. Discarded mineral oil; even in summer in northern my country, due to the high density and high kinematic viscosity of waste mineral oil, in order not to affect the normal delivery of the on-site mixed delivery pump, it can only be added in a small amount to diesel oil

Abstract

The invention discloses a porous granular ammonium oil explosive oil phase material with low cost, clean and environment-friendly, and high performance and a preparation method thereof. The oil phase of the porous granular ammonium oil explosive of the present invention is composed of (mass%) 88%-94% of hydrogenated heavy oil, 3%-6% of calorific value increasing agent and 3%-6% of antifreezing agent. The porous granular ammonium oil explosive of the present invention has good oil solubility in the oil phase, can add waste mineral oil to realize the reuse of waste oil energy, and has a good environmental protection effect; at the same time, the prepared explosive has excellent blasting performance and low production cost. It is suitable for industrial production and popularization.

Description

technical field [0001] The invention belongs to the technical field of ammonium oil explosives in industrial explosives, in particular to a porous granular ammonium oil explosive oil phase material and a preparation method thereof. Background technique [0002] Porous granular ammonium fuel explosive has been widely used all over the world because of its simple components and process, low production cost and high safety. The use of porous granular ammonium oil explosives in my country is mainly concentrated in open-air blasting projects. The "13th Five-Year Plan" of the national civil explosive industry also clearly requires the development of porous granular ammonium oil explosives, especially the production of porous granular ammonium oil explosives on site.
